SPECIFICATION forming part of Letters Patent No. 416,670, dated December 3, 1889.

Application iiled February l, 1889. SerialANo. 298,409. (No model.)

To all whom, t may concern.-

Be it known that I, GEORGE WILLIAM DEN- ZER, a citizen of the United States, residing at Kelleys Island, in the county of Erie and State of Ohio, have invented certain new and and exact description of the inventiomwhich` will enable others to make and use the same.

I-Ieretofore the lrequisite temperature of the oil to accomplish combustion has been reguf lated by means of an insulating coat of material around the pipe conveying oil t0 the burner-nozzle; but when this method is employed it is impossible to change the temperature or regulate to suit the various oils, or when it is desired to use larger or smaller quantities, while in use.

My invention relates to an injector-burner for hydrocarbons; and it consists in the construction and arrangement of parts hereinafter described and claimed.

The Object of my invention is to provide an injector-burner for hydrocarbon furnaces, which consists in the construction of a burner for injecting oil, steam, and air into the firebox of furnaces.

A further object of my invention is to provide a simple, cheap, and durable injectorburner of the character above described.

I attain these objects by the device illustrated in the accompanying drawing, wherein is shown a longitudinal vertical section of the same.

In the drawing, A represents the nozzle proper of the injector, having internallythreaded flange ot on its inner and a threaded channeled plug, as a', inserted through its upper side.

B is a jacket or outer cylinder secured to the iiange ct and having its opposite end Inovably secured in a collar C, surrounding the center of the burner. This end is held in place by a steam-tight joint l), secured to the collar by suitable threads. This construction permits a longitudinal movement of the jacket without permitting. the escape of the steam which it incloses.

D is the injector-burner tube or cylinder extending from below the nozzle below the jacket, to form a space between and back beyond the collar C. This cylinder is divided at the collar which unites the two ends thereof. Between the secured ends of cylinder D is placed the edges of the flanged end of an internal tube' E, which extends forward a short distance from the cylinder for the entire length of the space between the collar and nozzle. The rear end of the cylinder D is secured in an annular collar F, having a series of air-openings f therein. Around this collar F is placed a sliding sleeve F', provided with openings registeringwith the openings in the collar when properly adjusted. Itis held in its adjusted position `by a thumbscrew f, extending through the same into the collar. The rear edge of the collar F is bent down and internally threaded, with which threads engage. the threaded end of a cylindrical adjusting-pipe G, having a handwheel G rigidly secured thereon. Its outer end is bent up to form a ilange g, against which abuts a packing-joint H of an annular coupling H, into which leads an oil-supply pipe h.

To .the interior of the rear end of the adj listing-tube is tightly litted a valve-seat I, in the forward face of which is secured the oil-tube J, which extends forward and has its end capped with a spraying-nozzle J, supported by and extending through a steamnozzle K, located within the nozzle A, the several nozzles being arranged to permit the passage of steam and air through the same.

L is a perforated tube inserted in the end of the coupling H, its inner end being reduced to form an annular space Zbetween the same and the coupling, and into which the oil is forced, the perforations-being made in the reduced portion and located below the oil-pipe h.

The needle-valve O passes through a plug o in the end ofthe tube L, and enters the valveseat to regulate the iiow of oil.

B represents a steam-pipe, which entersv the space between the cylinder D and jacket B, the steam escaping through the channel a into nozzle K.

The operation is as follows: The oil is introduced through the pipe h and passes through tube J and is ejected at the end of Ico the nozzle J', the` quantity of oil being regulated by valve O. The position of the nozzle J is regulated in the nozzle K by the pipe G, which on being turned by handle G forces the same in or out, as the case may be. To heat the oil before it reaches the nozzle, steam is forced in the burner-pipe B and in the space between the jacket and the cylinder D, heating the air-space and the oil in the tube. The steam is then ejected from the nozzle K. To regulate the temperature in the cylinder D, airis permitted to circulate in the saine, it entering the cylinder through openings f, the amount being governed by thesleeve F. rlhe tube E prevents the cold air from coming in direct contact with the steam-heated portion, which enables a more positive and quicker change in the temperature of the oils. The oil is then forced out of the nozzle A and the oil, steam, and air commingled and ignited.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. In an injector-burner, the combination, with the divided cylinder and a jacket surrounding the outer end of the same, of an oiltube extending through the center of the cyl- 2. In an injector-burner, the combination,

with the divided cylinder D, the jacket B, partially surrounding the same, the outer nozzle A, having a channeled plug a extending therethrough,an inner steam-nozzle supported by said plug, a collar C, having a steam-pipe lea-ding into the same, a perforated collar F on the end of cylinder D, a regulating-slide on collar F', an adjusting-tube G in the end of collar F, the coupling I'I on the outer end of tube G, having an oil-tube leading into the same, a perforated tube L in said coupling, an oil-tube J, leading from the tube L, having a nozzle on its end,a needle-valve O, and an internal tube E, surrounding the oil-tube, substantially as described.

In Witness whereof I hereunto set my hand this 28th day of January, 1889. i

GEORGE WILLIAM DENZER.
